A gap is provided between the oil-proof and air-permeable structure 13 and the inner wall of the suction nozzle 112, and the gap can form a part of the pressure relief channel 100. The oil-proof and air-permeable structure 13 can prevent the liquid substrate in the liquid storage cavity 1110 from leaking out, and can be configured for pressure relief during liquid injection, to prevent liquid leakage caused by poor pressure relief of the liquid storage cavity 1110.

In this embodiment, the oil-proof and air-permeable structure 13 may be in a shape of a sheet. Specifically, the oil-proof and air-permeable structure may have a thin film structure. In this embodiment, the oil-proof and air-permeable structure 13 is an oil-proof and air-permeable film. Certainly, it may be understood that in some other embodiments, the oil-proof and air-permeable structure 13 is not limited to being an oil-proof and air-permeable film.

In this embodiment, there are two oil-proof and air-permeable structures 13, and the two oil-proof and air-permeable structures 13 are arranged on the first side 111a and the second side 111b. Certainly, it may be understood that in some other embodiments, there may be one oil-proof and air-permeable structure 13, and the oil-proof and air-permeable structure 13 may be only arranged on the first side 111a or only arranged on the second side 111b. In this embodiment, the oil-proof and air-permeable structure 13 includes a sheet-shaped body 131 and two extension portions 132, and the two sheet-shaped bodies 131 of the two oil-proof and air-permeable structures 13 may be arranged on the first side 111a and the second side 111b of the fitting portion 1112. The two extension portions 132 of each oil-proof and air-permeable structure 13 are respectively arranged on two opposite sides of the sheet-shaped body 131, and extend toward the third side 111c and the fourth side 111d respectively. By arranging the oil-proof and air-permeable structure 13 on two sides or four sides of the fitting portion 1112, pressure relief can be performed in a plurality of directions. That is, when the vaporizer 10 is placed in five directions other than the upside-down direction for liquid injection, pressure relief can all be performed, thereby achieving multi-angle pressure relief, ensuring the convenience of liquid injection of the vaporizer 1 and the reliability of pressure relief, and ensuring user experience. In some other embodiments, the oil-proof and air-permeable structure 13 may have only one extension portion extending toward the third side 111c or the fourth side 111d.

In this embodiment, the vaporizer 10 further includes a vent pipe 14. The vent pipe 14 is arranged in the vaporization shell assembly 11. Specifically, the vent pipe 14 is arranged in the vaporization shell 111, where one end thereof may be connected to the vent hole 1117, and the other end thereof may be inserted from the seal sleeve 126 into the liquid guiding hole 1213, and in communication with the vent hole 1117 and the liquid guiding hole 1213.

The first blocking member 151 may be a ball, and its diameter may be slightly larger than the aperture of the liquid inlet channel 1211, thereby blocking the liquid inlet channel 1211. Certainly, it may be understood that in some other embodiments, the first blocking member 151 may alternatively be a valve pipe. The first elastic body 152 may be a spring. One end of the spring may be connected to the first blocking member 151, and the other end thereof may abut against a wall surface of an end of the first track 1212 away from the first via 1114. Pushed by an external force, the first blocking member 151 may move to the end away from the first via 1114 under the action of the first elastic body 152, thereby making the liquid inlet channel 1211 open. When the external force is withdrawn, the first blocking member 151 may be reset under the action of the first elastic body 152 to block the liquid inlet channel 1211, so as to prevent the liquid substrate in the liquid storage cavity 1110 from leaking out.

In this embodiment, the second blocking assembly 16 includes a second blocking member 161 and a second elastic body 162. The second blocking member 161 may be a ball, and its diameter may be slightly larger than the aperture of the pressure relief channel 100, thereby blocking the pressure relief channel 100.

One end of the spring may be connected to the second blocking member 161, and the other end thereof may abut against a wall surface of an end of the second track 1214 away from the second via 1114. Pushed by an external force, the second blocking member 161 may move to the end away from the second via 1114 under the action of the second elastic body 162, thereby making the pressure relief channel 100 open. When the external force is withdrawn, the second blocking member 161 may be reset under the action of the second elastic body 162 to block the pressure relief channel 100, so as to prevent the liquid substrate in the liquid storage cavity 1110 from leaking out. It may be understood that, in some other embodiments, the second blocking assembly 16 may be omitted.

The liquid level detection assembly 19 is configured to detect a liquid level in the liquid storage cavity 1110, and transmit detected liquid level information to the liquid injection device 2. The liquid level detection assembly 19 directly or indirectly measures and infers the liquid volume in the liquid storage cavity 1110 by detecting the electrical characteristic of the liquid level change (that is, a liquid volume change) in the liquid storage cavity 1110. When the liquid level in the liquid storage cavity 1110 reaches a set threshold, the liquid injection device 2 may stop a liquid injection action according to the liquid level information. When the liquid level of the liquid storage cavity 1110 is lower than the set threshold, the liquid injection device 2 may start the liquid injection action according to the liquid level information, and then automatic liquid injection and automatic starting and stopping can be realized, which avoids leakage due to an excess of the liquid substrate in the liquid storage cavity 1110, and can further prevent dry burning, to avoid production of harmful substances. The set threshold may include a first threshold and a second threshold. The first threshold may be greater than the second threshold. When the first threshold is reached, the liquid injection device 2 may stop liquid injection. When the second threshold is not reached, the liquid injection device 2 may start liquid injection.

In this embodiment, the liquid level detection assembly 19 includes a first detection unit 191 and a second detection unit 192. The first detection unit 191 and the second detection unit 192 may be spaced apart at two opposite sides of the liquid storage cavity 1110, and may be distributed diagonally in a high-and-low manner, so as to ensure that the liquid storage volume in the liquid storage cavity 1110 can still be detected when vaporizer 1 is placed in five directions other than the upside-down direction.

The second channel 527 is parallel to the first channel 526 and in communication with the guide channel 5210, and one end thereof is in communication with the outside. The second channel 527 is configured for mounting and guiding of the pressure relief member 70.

In this embodiment, the base 52 is provided with an air flow through hole 528. The air flow through hole 528 may be in communication with the liquid storage member 53, and configured for ventilation of the liquid storage member 53, so that it is convenient for liquid flowing of the liquid storage member 53, and the liquid storage cavity 53 can be restored automatically after the liquid supply mechanism 60 finishes liquid supply. The air flow through hole 528 is in communication with the first channel 526, located on a section of the first channel 526 arranged away from the guide channel 5210, and located between the first limiting step 5261 and the second limiting step 5262. When the liquid injection member 611 moves away from the guide channel 5210, gas can be brought into the liquid storage member 53, so that the liquid storage member 53 is restored. Certainly, it may be understood that, the air flow through hole 528 may be omitted.

As shown in FIG. 23 and FIG. 24, in this embodiment, the liquid storage member 53 may be a flexible member or an elastic member. In this embodiment, the liquid storage member 53 may be a soft plastic part, and may specifically have a capsule structure. The liquid storage member 53 is sleeved on the sleeve portion 522 and fixed with the sleeve portion 522 through interference fit. a liquid storage tank 530 may be formed inside the liquid storage member 53, and the liquid storage tank 530 is configured to store the liquid substrate.

The partition assembly 56 is movably arranged in the first channel 526 and may be configured to partition the air flow through hole 528 and the first channel 526, thereby preventing the liquid substrate in the liquid storage tank 530 from leaking from the air flow through hole 528 into the first channel 526 and entering the liquid injection member 611. In some embodiments, the partition assembly 56 includes a third blocking member 561, a third elastic body 562, and a fixing sleeve 563. The third blocking member 561 may be a ball, and the diameter of the third blocking member 561 may be slightly larger than the aperture of the air flow through hole 528. The third blocking member 561 may move between the first limiting step 5261 and the second limiting step 5262, and is limited by the first limiting step 5261 and the second limiting step 5262. The third blocking member 561 may move under the action of the third elastic body 562, and then open or block the air flow through hole 528. One end of the third elastic body 562 may be connected to the third blocking member 561, and the other end thereof extends into the fixing sleeve 563 and abuts against the fixing sleeve 563. The third elastic body 5262 may be a spring.

When the liquid injection member 611 moves toward the electronic vaporization device 1, the third elastic body 5262 may drive the third blocking member 561 to move toward the second limiting step 5262 to abut against the second limiting step 5262. When the liquid injection member 611 moves away from the electronic vaporization device 1, the third blocking member 561 may be pushed, and the third elastic body 5262 is in a contracted state. The third blocking member 561 may be pushed to the air flow through hole 528.

The liquid injection connection assembly 61 includes a liquid injection member 611 and a slider module 612. The liquid injection member 611 at least partially runs through the first channel 526. The slider module 612 is connected to the liquid injection member 611 and may move under the action of an external force, thereby driving the liquid injection member 611 to move. When the electronic vaporization device 1 is mounted in the accommodating cavity 4220, the slider module 612 of the liquid injection connection assembly 61 may move from the second position to the first position, and when the liquid injection connection assembly 61 moves to the first position, that is, when the slider module 612 moves to the first position, the liquid injection member 61 is connected to the electronic vaporization device 1 and in communication with the liquid storage tank 530. When the electronic vaporization device 1 is removed from the accommodating cavity 4220, the liquid injection connection assembly 61 may move to the second position and be disconnected from the electronic vaporization device 1.

As shown in FIG. 2 to FIG. 4 and FIG. 28, in this embodiment, the liquid injection member 611 may be tubular, may move along the side wall perpendicular to the electronic vaporization device 1, and is inserted into the electronic vaporization device 1 along the side wall perpendicular to the electronic vaporization device 1 when the slider module 612 moves to the first position, thereby implementing liquid injection.

The radial dimension of the second pipe section 6112 may be greater than the radial dimension of the first pipe section 6111, and the radial dimension of the second pipe section 6112 may be corresponding to the radial dimension of the second limiting step 5262 in the first channel 526. When there is no liquid injection or the liquid injection is finished, the second pipe section 6112 may be arranged in the first channel 526, and the pipe wall of the second pipe section 6112 may be close to the channel wall of the first channel 526 and a role of sealing is played for the liquid flowing channel 523, thereby having the effect of preventing liquid leakage. The radial dimension of the first limiting pipe section 6113 may be larger than the radial dimension of the second pipe section 6112. The first limiting pipe section 6113 is configured for fitting and limiting with the slider module 612, thereby avoid falling out from the slider module 612. An annular limiting boss is arranged at an end of the first limiting pipe section 6113 connected to the first pipe section 6111. A liquid injection channel 6110 is formed inside the liquid injection member 611, and the liquid injection channel 6110 is formed in the first pipe section 6111, the second pipe section 6112, and the first limiting pipe section 6113, and may be in communication with the liquid flowing channel 523 when the liquid injection member 611 is inserted into the electronic vaporization device 1. The liquid injection channel 6110 may be configured for injecting the liquid substrate in the liquid storage tank 530 into the liquid inlet channel 1211 of the electronic vaporization device 1 and then into the liquid storage cavity 1110. An end of the first pipe section 6111 away from the first limiting pipe section 6113 is provided with a liquid outlet 6114, and the liquid outlet 6114 extends along the side wall of the first pipe section 6111 and is approximately U-shaped. Certainly, it may be understood that in some other embodiments, the liquid outlet 6114 is not limited to being U-shaped. The liquid outlet 6114 extends to the side wall of the first pipe section 6111, and then when the first pipe section 6111 abuts against the first blocking member 151, the liquid substrate in the liquid injection channel 6110 can still be outputted.

The clamping bone 612b may run from the guide groove 4210 into the placement groove 4211, when the liquid storage structure 50 is placed on the placement groove 4211, the clamping bone 612b may be inserted into the clamping hole, thereby being connected to the slider 6121, and simultaneously clamping the liquid storage structure 50 with the holder 42. That is, the clamping structure arranged between the holder 42 and the liquid storage structure 50 may be the clamping bone 612b and the clamping hole.

In this embodiment, the driving unit 62 may be an electric drive assembly. Certainly, it may be understood that in some other embodiments, the driving unit 62 is not limited to being an electric drive assembly. The driving unit 62 may be connected to the push plate 6122, and may drive, by receiving a control instruction from the control assembly 44, the slider module 612 to slide toward the partition wall 423, or to slide away from the partition wall 423, or to stop sliding. In this embodiment, the driving unit 62 includes a drive motor 621 and a transmission mechanism 622. The drive motor 621 may be connected to the transmission mechanism 622 for driving the transmission mechanism 622 for transmission. In this embodiment, the drive motor 621 may change the moving direction of the slider module 612 through forward and reverse rotation. The drive motor 621 may be connected to the control assembly 44, and may be started or shut down by the control assembly 44. The transmission mechanism 622 may be connected to the push plate 6122, and may drive the push plate 6122 to move under the drive of the drive motor 621. In this embodiment, the transmission mechanism 622 includes a sliding sleeve 6221 and a transmission screw 6222, and one end of the transmission screw 6222 is connected to the drive motor 621. The sliding sleeve 6221 is sleeved on the transmission screw 6222 and connected to the push plate 6122 through arrangement of a connecting piece 64. The drive motor 621 may drive the transmission screw 622 to rotate, and then drive the sliding sleeve 6221 to slide on the transmission screw 6222, thereby driving the push plate 6122 to move.

In this embodiment, the power assembly 63 is mounted in the main unit 40 and runs into the placement groove 4211 of the first support 421. Specifically, the power assembly 63 may be arranged in the receiving cavity 411. In this embodiment, the power assembly 63 includes a power pump 631 and a connection pipeline 632.

The connection pipeline 632 may be connected to the power pump 631 for outputting a power source to the spacing 54 to squeeze the liquid storage member 53 to output the liquid substrate. Specifically, the power source may be gas. When the liquid storage structure 50 is mounted on the holder 42, one end of the connection pipeline 632 may be connected to the connection through hole 524, thereby realizing gas input into the spacing 54. It may be understood that, in some other embodiments, the power source is not limited to gas, and the power assembly 63 is not limited to including a power pump 631 and a connection pipeline 632.

As shown in FIG. 2 to FIG. 4 and FIG. 29, in this embodiment, the liquid injection device 2 further includes a pressure relief member 70. The pressure relief member 70 is arranged in the liquid storage structure 50, specifically located on the base 52, and movably mounted in the second channel 527, and may run through the second channel 527, and be inserted into the electronic vaporization device 1. In this embodiment, the pressure relief member 70 may be connected to the slider module 612, and then may be driven to move by sliding of the slider module 612. When the slider module 612 moves to the first position, the pressure relief member 70 is connected to the electronic vaporization device 1 and may release the pressure of the electronic vaporization device 1; and when the slider module 612 moves to the second position, the pressure relief member 70 may be disconnected from the electronic vaporization device 1. Specifically, the slider 6121 may be sleeved on the pressure relief member 70 and simultaneously be connected to the pressure relief member 70 and the liquid injection member 611. The pressure relief member 70 and the liquid injection member 611 are spaced apart. Specifically, the pressure relief member 70 and the liquid injection member 611 may be spaced apart along the width direction of the guide channel 5210, and are parallel to each other. That is, when the liquid injection member 611 is inserted into the electronic vaporization device 1, the pressure relief member 70 is also inserted into the electronic vaporization device 1, and when the liquid injection member 611 injects liquid, the electronic vaporization device 1 may perform pressure relief simultaneously, thereby improving the safety of use of the electronic vaporization device 1, to ensure the smooth progress of the liquid injection. It should be noted that, during the withdrawal process of the pressure relief member 70, the process in which the liquid injection member 611 seals the liquid flowing channel 523 is shorter than the process in which the liquid injection member 611 is withdrawn from the electronic vaporization device 1, thereby preventing the liquid substrate in the liquid storage structure 50 from leaking after the liquid injection member 611 is withdrawn from the electronic vaporization device 1.

In this embodiment, the pressure relief member 70 is tubular and has a hollow structure with two run-through ends, and a pressure transmission channel 710 may be formed inside. The pressure relief member 70 may move along the side wall perpendicular to the electronic vaporization device 1, and may be inserted into the electronic vaporization device 1 along the side wall perpendicular to the electronic vaporization device 1 when the slider module 612 moves to the first position, thereby avoiding the problem of liquid mixing during liquid changing. In this embodiment, the pressure relief member 70 includes a third pipe section 71, a fourth pipe section 72, and a second limiting pipe section 73. The third pipe section 71, the second limiting pipe section 73, and the fourth pipe section 72 are sequentially connected, and the pressure transmission channel 710 is formed in the third pipe section 71, the second limiting pipe section 73, and the fourth pipe section 72. The third pipe section 71 may run through the base 52 and run through the partition wall 423 to be inserted into the second track 1214 sequentially from the first relief hole 211b and the second via 1115, so that the second blocking assembly 16 can be moved away from the second via 1115, to open the pressure relief channel 100 and communicate the pressure transmission channel 710 with the pressure relief channel 100. The radial dimension of the fourth pipe section 72 is larger than the radial dimension of the third pipe section 71. The fourth pipe section 72 may be arranged in the second channel 527. The radial dimension of the second limiting pipe section 73 may be greater than the radial dimension of the fourth pipe section 72, and is configured for limiting and mounting with the slider 6121.

In this embodiment, the liquid injection device 2 further includes a position detection assembly 80. The position detection assembly 80 is mounted on the holder 42. Specifically, the position detection assembly is mounted on the first support portion 421a of the first support 421, connected to the control assembly 44, and configured to detect a position of the liquid injection connection assembly 61. Specifically, the position detection assembly 80 may detect a position of the slider module 612, and then know a position of the liquid injection member 611. In addition, the position detection assembly 80 may transmit the detected position information to the control assembly 44, thereby realizing liquid injection into the electronic vaporization device 1 more accurately. When the liquid injection connection assembly 61 is at the first position, that is, the slider module 612 is at the first position, and the liquid injection member 611 is in communication with the electronic vaporization device 1, the control assembly 44 may start the power assembly 63 to drive the liquid storage tank 530 to output the liquid substrate. When the liquid injection connection assembly 61 is located at the second position, that is, when the slider module 612 is located at the second position, and the liquid injection member 611 is disconnected from the electronic vaporization device 1, the control assembly 44 may enter the standby state. In this case, the power assembly 63 is in a shut-down state.

As shown in FIG. 20, in this embodiment, the position detection assembly 80 includes a first detection unit 81 and a second detection unit 82. The first detection unit 81 is arranged corresponding to the first position. Specifically, the first detection unit may be located in the first support portion 421a of the first support 421, and arranged corresponding to the first position. The second detection unit 82 corresponds to the second position. Specifically, the second detection unit is located in the first support portion 421a and is arranged corresponding to the second position. Both the first detection unit 81 and the second detection unit 82 are connected to the control assembly 44.

In this embodiment, both the first detection unit 81 and the second detection unit 82 may be connected to the control assembly 44 by arranging a conductive structure, and the conductive structure may be selected to be a wire. When the slider module 612 slides to the first position, the slider module 612 may be in contact with the first detection unit 81, and the first detection unit 81 may transmit position information of the slider module 612 to the control assembly 44. The control assembly 44 sends a control instruction to the power assembly 63, and the power assembly 63 is started, and may output a power source to the spacing 54, to squeeze the liquid storage member 53 to output the liquid substrate. When the slider module 612 slides to the second position, the slider module 612 may be in contact with the second detection unit 82, and the second detection unit 82 may transmit the position information of the slider module 612 to the control assembly 44. The control assembly 44 may enter the standby state.

In this embodiment, the first detection unit 81 may include two first detection electrodes 811 that are opposite and spaced apart. When sliding to the first position, the push plate 6122 may be engaged between the two first detection electrodes 811, and conduct the two first detection electrodes 811. It may be understood that, in some other embodiments, the first detection unit 81 is not limited to including two first detection electrodes 811. In some embodiments, the first detection unit 81 may be a position sensor or other conventional position detection devices.

In this embodiment, the second detection unit 82 may include two second detection electrodes 821 that are opposite and spaced apart. When sliding to the second position, the push plate 6122 may be engaged between the two second detection electrodes 821, and conduct the two second detection electrodes 821. It may be understood that, in some other embodiments, the second detection unit 82 is not limited to including two second detection electrodes 821. In some embodiments, the second detection unit 82 may be a position sensor or other conventional position detection devices.

As shown in FIG. 2 and FIG. 4, in this embodiment, the liquid injection device 2 further includes a charging structure 90. The charging structure 90 may be connected to the control assembly 44 and may be connected to a charging support 424. When the electronic vaporization device 1 is mounted in the accommodating cavity 4220, the liquid injection device 2 can not only inject liquid into the electronic vaporization device 1, but also charge the electronic vaporization device 1 through the charging structure 90.

When the electronic vaporization device 1 is mounted in the accommodating cavity 4220, the control assembly 44 detects that there is an electronic vaporization device 1 in the accommodating cavity 4220, and the control assembly 44 may send a control instruction to the drive motor 621. The drive motor 621 may rotate in a first direction, to drive transmission of the transmission mechanism 622, thereby driving the entire liquid injection connection assembly 61 to move from the second position to the first position, that is, driving the slider module 612 to move from the second position to the first position, and then driving the liquid injection member 611 to run from the partition wall 423 to the accommodating cavity 4220 and runs into the first track 1212 of the electronic vaporization device 1, to communicate the liquid injection channel 6110 with the liquid inlet channel 1211, and simultaneously driving the pressure relief member 70 to run from the partition wall 423 to the accommodating cavity 4220, and run into the second track 1214 of the electronic vaporization device 1, to communicate the pressure transmission channel 710 with the pressure relief channel 100 for pressure relief.

The push plate 6122 slides to the first position and is engaged between the two first detection electrodes 811. When detecting that the push plate 6122 slides to the first position, the first detection unit 81 transmits position information of the liquid injection connection assembly 61 to the control assembly 44. The control assembly 44 sends a start instruction to the power assembly 63, to start the power assembly 63 to output the power source to the spacing 54, to squeeze the liquid storage member 53 to output the liquid substrate. When detecting that the liquid level in the liquid storage cavity 1110 reaches a first threshold, the liquid level detection assembly 19 sends liquid level information to the main control board 23, and the liquid level information is sent to the control assembly 44 through the main control board 23. The control assembly 44 sends a stop instruction to the power assembly 63, and sends a control instruction to the drive motor 621, so that the drive motor 621 rotates in a second direction, to drive transmission of the transmission mechanism 622 in the opposite direction, thereby driving the slider module 612 to move in the direction of the second position, and then driving the liquid injection member 611 to be withdrawn from the electronic vaporization device 1 and reset. When the slider module 612 slides to the second position, the push plate 6122 is engaged between the two second detection electrodes 821, and when the second detection unit 82 can detect that the push plate 6122 slides to the second position, the position information of the liquid injection connection assembly 61 is transmitted to the control assembly 44, and the control assembly 44 stops driving the power assembly 63 and the drive motor 621, and enters a standby state. That is, the entire liquid injection device 2 is shut down and in a standby state. When the user needs to inhale, the electronic vaporization device 1 may be pulled out from the accommodating cavity 4220.

The liquid flowing member 58 is mounted in the accommodating groove 5211 and may be configured to communicate the liquid flowing hole 5222 with the liquid injection member 611. In this embodiment, the liquid flowing member 58 includes a liquid flowing portion 581 and a sealing portion 582, and the liquid flowing portion 581 is in a shape of a square block. The sealing portion 582 is connected to one side of the liquid flowing portion 581 and has an integral structure with the liquid flowing portion 581.

The liquid inlet through hole 5812 is in communication with the insertion channel 5811. When the liquid injection member 611 moves to the first position, the liquid substrate in the liquid storage tank 530 may enter the insertion channel 5811 from the liquid inlet through hole 5812, and enter the liquid injection channel 6110 from the end of the liquid injection member 611. When the liquid injection member 611 moves to the second position, the liquid injection member 611 may be inserted into the insertion channel 5811, and its wall surface may cover an output end of the liquid inlet through hole 5812, thereby sealing the liquid inlet through hole 5812.
